Bruno, It is slow because for every layer in the map the web tier sends 2 requests (Authenticate + GetResourceContent) to the server. So in your map case there would be a minimum of 400 requests to the server. This is something we are aware of and would like to change. We have some test maps with over 700 layers. Ideally, we would like to change this down to about 2 requests regardless of the # of layers- ie: Authenticate + CreateMap. In order to do this we need to move the map creation to the server side and then serialize back to the web the created map object.

When a use the MgMap API Create it takes about 20 seconds But if i use the GetResourceContent it almost instantly. I wonder why this function is so slow. The only thing i'm trying to do is to read this MapDefinition to retreive information about a layer his resource Id his group hierarchy and his display order.
